Headphones so far ES-10 and T5p, IEM almost all the stuff on my profile and few more I have not listed.
Right now I am using it as an amp alone. In order for me to evaluate this unit I must consider three things:
1)How does it perform as an stand alone amp?
2)How does it work as an ipod dac/amp?
3)How does it work as a DAC/amp using the camera kit and onkyo app?
If have left out the DAC alone to another amp feature (it does that using the fixed out feature) but for me that beside the point as it will be too large for me to carry it.
The selling feature of this unit is the Advanced AL32 processing and this is why to me the most important feature is 2). Currently I am using it as amp alone to preserve battery.

It is too soon to tell as I need to let it burn for 200 hour (for sake of mind) and than set down and listen to the same track over and over agin on different devices, trying to ensure my mind is not tricked into hearing things and than evaluate.
So far so good, it is a device for IEM user, do not expect it to driver anything demanding as it will fail. (Sorry for the user who was hoping to drive the LCD2)
